摘要

目前我国高土心墙堆石坝的设计思想是在总结小浪底这类筑坝经验的基础上建立的，只有200 m级以下的资料可供参考，为此采用数值分析方法对居于心墙坝世界前列的深厚覆盖层300 m级高土心墙堆石坝进行进一步研究，探讨了心墙堆石坝填筑与蓄水的全过程，并分析了坝体、心墙的应力与变形特征。计算结果表明，300 m级高土质心墙堆石坝变形、应力均在可接受的范围内，理论上是可行的。

Abstract

At present the design concept of high earth core dams in China is on the base of experience of building dams such as Xiaolangdi Dam; and there are some reference data only for 200 m level. In order to study the 300m level high earth core dams with thick overburden layer which is in the most advanced world level the whole filling and water storage process is simulated by FEM

and the 3D stress and deformation characteristics of dam body and earth core are analyzed. The results show that the defromations and stresses of 300m level high earth core dams are in the allowable scope; therefore

it is feasible theoretically.
